Alives is right...
imagine u have a rope with 2x 1kg weights on each end and a pulley in the middle...
1.
the rope is 1M long.. u attach the pulley on the ceiling.. on each side u have 50CM and 1KG pulling
u give the one weight a push upward.. what u'll see happening is: one weight moves upwards and one downwards.. only limited by the resistance of the pulley
2.
the rope is 100M long.. u attach the pulley on the ceiling.. on each side u have 50M and 1KG pulling
the result is the same speed as 2, in almost perfect testconditions (no wind etc)
1-2nd.
the rope is 1M long.. u attach the pulley on the ceiling.. on each side u have 50CM and on one side 1KG pulling..
u pull the rope and still need to pull the rope till its on the top..
2-2nd.
the rope is 100M long.. u attach the pulley on the ceiling.. on each side u have 50M and on one side 1KG pulling..
u pull the rope and still need to pull the rope till its on the top.. BUT AL LOT LONGER THAN 1-2nd!!
the only thing u now have to imagine is :
the rope = tubing
the weight = water
the pulley = tap,small tube or sth..
the GPH is calculated on heigth difference of the inlet and outlet... it DOESN'T matter if the tubing is gone 20M up and down.. The pump provides the push and the gravity does the rest of the job for u!
( but the pump has to continually push or else the flow stops)
SO NOW U KNOW!! THE GPH IS LIMITTED BY INLET-OUTLET HEIGHT DIFFERENCE AND THE BOTTLENECKS IN THE TUBE!!
in my setup the water loops every 1.5 seconds!
